Hey guys! Sorry my bad english, this is my first build guide and ill try to show you why lee sin is my main... HE IS FU$@$ AEWSOME!

Lee sin has a large potential in jungle with your ganks, but honestly I never can jungle very well with him, so I tried to specialize in lane.

I choose Quints of desolation cuz nothing more efficient than armor penetration. With quints, marks, n masteries u should middling 30 armor pen, its a lot of armor pen and finish with however tank appears beside u. Armor n magic resist per level(its like core runes for lee sin).

Focus on attack. Any points on defense. Not much to say about it.

So lets start it.

Always I start with dorans blade. Why? Cuz dorans blade give to u a little bit of life steal, health, n attack damage. This is what u need for: strong beginning to dominate your lane.

WHY 3 DORANS BLADE?
3 dorans blade give to u 240 health, 30 attack damage, n 9 life steal, a great start to harass your enemies.

Mercury's boots give to u magic resist. I think this is the excellent item for everyone. With yours runes it gives to u alot of magic resist.

Force of nature give to u a lot of magic resist too n heath regenaration... armog make u a off-tank.. bloodthirster give to u life steal (with your ironwill u has lifesteal like a hell) n trinity force... ohhhh trinity force.. i love u so much... mov speed, burst damage increased with sheen, reduction enemy's moviment speed, life a little bit... well, a great item for everyone.

Flash to chase or come near to a minion to safe guard (it gives to u epic escapes..) n ignite to x1 against a lifesteal machine or a tank.

AT LVL 6

Buy your dorans n start to harass the enemy. Use your Q to do damage the enemy, always with attention to escape with your W if it is necessary. Use your Q to mark the enemy, n use again to jump to him, even if he was under tower, n immediately use your W to near ally champ or minion. Keep harassing them, always with attention. Dont forgot to farm, A LOT.

AFTER LVL 6

Oh, my favorite part of the game. I has my DRAGON'S RAGE! Now u can get they whatever they are. Use your Q to mark the enemy, hit him, use your Dragon's Rage to kick him, n use your Q to come near, after this use your E n E again to slow him, n get dat kill. In Team fight try to kick the enemy under your turret. For dat your E to slow him, go behind n KICK IN YOUR FACE UNDER UR TURRET! your allies will help u to finish him. If make necessary use your flash to jump behind. Always get some wards, to put over walls n jump for escape the unexpected situations.
